Frequency band selection
Every GSM network operates on one set of frequency bands.
(See “Frequency band selection” on page 28.) The AirCard is
designed to change frequency bands automatically as required
to obtain network service. You can also change frequency
bands manually from the Network tab of the Options window
(
Tools > Options > Network).
Note: Unless your service provider specifies otherwise, it is recom-
mended that you use the Auto setting.
Network selection
Depending on your location, you may be within the coverage
area of several networks. Your ability to obtain service on each
network is dependent on your account.
Your options for network selection are:
• Automatic—The AirCard automatically selects a network
based on your account and network availability.
• Manual—The AirCard scans the area and displays a list of
detected GSM networks. You can then choose from a list of
available networks.
If you select a network on which you cannot obtain service, the
message, “Failed to register with network” appears. You
should then choose a different network.
This option is set on the Network tab of the Options window
(
Tools > Options > Network).
